I have a power probe brand torch and it works great heat is adjustable and it holds quiet abit of butane and has different tips. I have soldered circuit boards to soldering eye glasses to soldering radio wiring

That's what I use. I gloop lots of copper together with that. And heat is never an issue.

Looks like I started writing this up a few days ago on this computer and never submitted it. I might as well finish it.

I don't know what you are planning to use it for, but I use a bernzomatic torch at work for sweating (soldering) copper pipes. The fuel is mapp gas.

Build quality: It is build like a tank. It gets carried loose in the plumbing bag, so it take abuse there. Then it goes under houses and gets thrown in the dirt, dropped, kicked, etc. I don't think there is much that you will do to it that will wear it out. We have been through a few, but they take punishment first.

Capacity: Whatever your tank size is. This is also going to be a limiting factor for you. I like a larger tank for work, but with whatever you are going to do with it, I am sure you will want a smaller tank. I bet you will want to take it to a field or where ever.

Heating power: Mapp gas burns hot, so there you go. It might be a bit to hot for you though. I know the bernzomatic will accept propane also. You might also be able to find a smaller tank in propane. It might work with butane.

Ease of use: A monkey could use it. The trigger/ignition acts as a safety; you have to switch it on to click it. It also has a gas on/off. You will have trouble with detail on this though because it is designed to get a copper pipe hot so that you can melt solder on it.
